xf86config?

I was reading a ~= four year old guide to linux, it's pretty good, but the gentlemen recommended using xf86config to configue X but I don't see it in the options for intalling on opensuse
turns up nothing. Now, I don't have any real complaints aganist X, so don't think I'm trying to fix anything. I am just being curious. I'm assuming that the tools name has changed or some such thing.
Thanks in advance
